Electric-heat tracing electricity consumption monitor for solar water heater

The utility model relates to an electric-heat tracing electricity consumption monitor for a solar water heater, which comprises a shell, a watt-hour meter, an input power socket and an output power supply socket. The watt-hour meter is arranged inside the shell; the input power socket and the output power supply socket are fixed on the shell; the input power socket is electrically connected with the input end of the watt-hour meter; the output power supply socket is electrically connected with the output end of the watt-hour meter; a plug connected with a tracing electrical heating element of the solar water heater is inserted into the output power supply socket; the plug of a power source is inserted into the input power socket to run the watt-hour meter; and therefore, the electric-heat tracing electricity consumption monitor for the solar water heater is formed. The monitor has simple structure, and convenient power transmission and power-down; a user can observe whether an electrical heater normally opera
